To all whom 'it mwy concern:

Be it known that I, RICHARD W. HAMANN, a. citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Nozzles for loiler-Flue Cleaners, of which the following m l. specification containing a full, elem, and exact description, reference being had tothe accompanying drawings, lormmg a part hereof.

My invention relates to u nozzle for boiler ihre cleaners, and the object of my invention is to provide a simple and inexpensive nozzle for boiler iue cleaners, which is adapted lor delivering jets of steam or compressed air into and through the boiler tubes or lines to remove the soot and like aci-.insulation therefrom.

To the above purposes, my invention consiste in certain nove features oi' construction and arrangement of ports, which will be here imiter more fully set forth, pointed out in Fixed in any suitable manner on the tube 8 is an operatin handle 11.

The lorwnrl end of the body 6 oi the nozzle is closed by a disk or plate 12, und formed in the center thereof is a straight aperture 13. Formed on opposite sides of this centrally disposed aperture, end adjacent the edges ol' the plate or disk 12, is e pair of apertures 14, which are approximately the saine diameter as is the aperture 13, and said apertures 14 being formed on slight angles relative the aperture 13, in order tliatthe jet-s of steam or air issuing l'roin seid apertures 14 will diverge slightly from the jet xssuillgI from the aperlure 13.

Formed in the foi-werd ortion of the body of the nozzle 6, and in t 1e seme horizontal plane with the apertures 13 and 14, is s. pair" of apertures 15; and formed through the body of nozzle 6, immediately to the rear of these apertures 15, is e pair of apertures 16,

, slightly larger in diameter than are said aperthe claims, and illustrated in the mr'onlpany- 'j in drawings, 1n which wigure l -is a horizontal seelion taken through the rear ort-ion ol' 1". boiler nud boiler setting,and s lowing my improved nozzlein position in the rear wall ol' the boiler setting; Fig. 2 is e horizontal section token through the center of the nozzle; Figv 3 is an end elevation of the nozzle.

Referring by numerals to the accompanyin drawin s:-1 designates a boiler, proed with t e usual tubes 2; and positioned in the usual boiler setting v Arranged in the roer woll ol' the boiler setting, directly op osito the conter oll the boiler tube are, is a unnel shaped housing 4, the wide open end of which opens toward the Iroer end of the boiler; und formed integral with the Outer or roar end of this housing,r 4 is `steam or compressed air supply pipe l0.

tures l5, and being formed on such angles relative the angles on which the apertures 15 ure formed as that the jets of steam or air issuini)r from said apertures 1.6 Will join `the jets of steam or air issuing from the apertures 1 5, a short dista-nre away from the nozzle.

Formed through opposite sides of the body (i of the nozzle and in the same pleno as the opi-Mures hereinbefore described is a pair of apertures 17, approximately equal in diameter to the diameter ol' the apertures 16; and formed through the rear )orton of the bod 6 of the nozzle, and in the seme plane wit i the plane occupied by the hereinhefore doscrihed apertures, is a 'ptir of apertures 18, slightly larger in diameter thon are the sperturos 17, and being forme-d ensueh ongles as that the jets of steam or air issuing from sold apertures 1S will moet 'the jets of steam or air issuing,r from the apertures 1.7, o short distunro away from the nozzle.

lt will be noted that the apertures 18 are paired with, the apertures 17, and the apertures Io ore paired 'with the apertures 15, to bring the corresponding j-ete el stoom or er! together a short distance :muy frm'n the nozzle, and this sinne orranffement may be carried out indefinitely by lengthen-ing the nozzle 6. And when steam or air is turned! on through the su ply ipe 10, it is delivered to the nozz e 6 y means of the pipe 8, and will issue from the various apertures or jet holes; and owing to the angularity of said apertures adiverging or fanlike series of jets of stdam or air will issue from the nozzle; and which jets all occu y the same horizontal or \vert1cal plane, e-

ending on the position of the nozzle, which is rotated by means o'r' the handle 11.

The jets of steam or air issuing from the apertures 16 and 18 are larger and, therefore, stronger than the jets issuing from the apertures 15 and 17; and, therefore, when the Jets issuilnT from the apertures 15 and 17 Join with the jets issuing from the apertures 1 6 and 18 the stronger pressure of the larger jets W` deflect the smaller jets so that the saine travel in approximate strai ht lines forward into the rear ends of the boer tubes and blow therethrough, and thus remove the soot and like accumulation. This action is graphically disclosed by dotted lines in Fig. 1.; and thus by the angular arrangement-and relative sizes of the apertures forming the jet openings, I am enabledtodeliver the approximate full pressure of the steam or air straight through the tubes; and, as a result, obtain a thorough cleaning action entirely through the tubes.

When the vdevice is in use, the pipe 8 and nozzle 6 are rocked in both directions by manipulating the handle 11, and thus the jets of steam or air are delivered over the entire tube area of the boiler.

The nozzle can be made in dilerent sizes to suit different conditions; and, in some instances, it may be found desirable to utilize a second set of apertures, or jet openings; and, whenrsuch arrangement is carried out, the two sets of apertures are preferably arranged at right angles to one another.

A device so constructed is very simple, inepensive, easily applied for use, and is very e icient in blowing soot and like accumula tion from the boiler tubes.
